Nuclear
Commissioning software for a sector where the regulator checks the evidence, not the assurance.
Nuclear projects — new-build reactors, SMR fleets, life extensions, outages, decommissioning — run on a safety classification that never lets a shortcut through: every hold point witnessed, every qualification certificate linked to the component it covers, every NCR tracked to disposition. Deskely holds that register in one place, from first concrete to final site release.

The problem
A spreadsheet cannot prove which safety-classified hold point was actually witnessed.
Nuclear commissioning runs across mechanical, electrical, I&C and civil contractors for years, each producing its own ITP records, NCRs and vendor documentation. When that evidence sits in separate systems, nobody can show a regulator the full record before a fuel load, outage return-to-service or site release decision.
Safety classification gets lost between contractors
SC1, SC2 and SC3 systems carry different QA rigour, but disconnected contractor records treat them the same or reconcile them by hand.
Hold points are witnessed, then forgotten
A witness sign-off in a paper binder is not the same as a queryable record the licensee's independent oversight function can check before a readiness review.
Qualification certificates sit apart from the installed component
Environmental and seismic qualification evidence lives in a vendor archive, disconnected from the specific component's manufacturer, model and serial number.
Outage and refuelling windows leave no room for reconciliation
Work orders, FME control and isolation boundaries change every shift, and a fixed return-to-service date does not wait for a spreadsheet to catch up.
What you get
Built for the safety classification, hold points and QA levels nuclear projects actually run on.
Model reactors, modules, outage work packages and decommissioning areas as tagged assets carrying their safety classification, qualification basis and ITP from day one.
Safety classification tracking
Every component and system carries its safety classification as a core attribute, so QA rigour and reporting can be filtered and gated accordingly.
Learn moreITP hold point records
Hold points captured with the witness's name, role, qualification and timestamp against the exact ITP revision executed.
Learn moreEquipment qualification traceability
Qualification certificates linked to the installed component's manufacturer, model and serial number, not a generic part number.
Learn moreOutage and refuelling work orders
Critical path work orders, FME control zones and isolation boundaries tracked live through a fixed-duration outage window.
Learn moreTurnover and certificates
System turnover, fuel load readiness and area release certificates issued only from signed, reviewable records.
Learn moreAI drawing parser
P&IDs, single line diagrams and equipment lists turned into a reviewed, safety-classified tag register instead of months of typing.
Learn moreHow it runs
From first concrete to final site release.
- 01
Classify and model the plant
Systems and components modelled with their safety classification, ITP reference and configuration baseline.
- 02
Test cold, hot and functional
Cold functional, hot functional and safety function tests signed against the component and hold point they cover.
- 03
Witness and disposition
Hold points witnessed by the right authority, NCRs tracked to disposition, before any readiness review.
- 04
Turn over and hand off
System turnover, fuel load readiness or area release issued from a complete, signed record set.
Side by side
Contractor binders versus one safety-classified record.
The question at every nuclear gate is the same one a regulator or independent oversight function will ask: can you show the hold point was actually witnessed?
| Aspect | Binders and spreadsheets | Deskely |
|---|---|---|
| Safety classification | Tracked inconsistently across contractor systems. | A core attribute on every tagged component and system. |
| Hold point witness records | Paper sign-offs filed by contractor. | Name, role, qualification and timestamp on every hold point. |
| Equipment qualification | Certificates in a vendor archive. | Linked to the installed component's serial number. |
| Outage work orders | Reconciled by hand every shift change. | Live status on work orders, FME zones and isolations. |
| Turnover and release | Assembled from scratch before the review. | Exported directly from the register used throughout. |

FAQ
Questions about nuclear.
Project types
The same safety-classified register, from first concrete to final decommissioning.
What changes between nuclear scopes is the safety classification, the qualification basis and which authority witnesses the hold point. The record types, the gates and the audit trail behind them do not.
New-build reactor commissioning
A new-build nuclear unit is commissioned system by system against a safety classification that never lets a shortcut through: SC1 systems get the tightest QA, the most hold points and the most scrutiny, and every one of them has to be traceable back to an approved design document. Deskely holds every component, system and hold point in one register, with cold functional testing, hot functional testing and fuel load readiness gates built in.
See this scope in detailSmall modular reactor (SMR) commissioning
SMR programmes are built on repeatability: factory-fabricated modules arrive with much of their QA history already established, and the site commissioning programme has to pick that history up rather than start from zero, while still proving every safety-classified system on-site. Deskely holds the factory QA record, the site ITP and the fleet-wide template in one register, so unit two starts from a proven baseline instead of a blank spreadsheet.
See this scope in detailNuclear plant life extension commissioning
Extending a reactor's operating life means replacing steam generators, reactor vessel internals, cabling and I&C systems that are approaching the end of their qualified life, each swap re-commissioned against the plant's original licensing basis rather than treated as a green-field install. Deskely holds the ageing management assessment, the replacement scope and the re-commissioning record in one register, so the extension case is built from evidence rather than assembled after the outage closes.
See this scope in detailNuclear outage and refuelling commissioning
A refuelling outage compresses a year's worth of maintenance, inspection and modification work into weeks, with the critical path measured in hours and every open work order a threat to the return-to-service date. Deskely holds every work order, FME boundary and post-maintenance test in one register, so outage control can see the true critical path instead of a status update assembled from a dozen contractor spreadsheets.
See this scope in detailNuclear decommissioning and waste management commissioning
Decommissioning reverses the commissioning logic: instead of proving a system is ready to operate, the programme has to prove a system, structure or site area is safe to release, characterising every waste stream and surveying every area before it leaves regulatory control. Deskely holds the dismantling sequence, the radiological survey record and the waste package chain of custody in one register, so site release is supported by a traceable dataset rather than a closeout report written from memory.
See this scope in detailNuclear fuel handling and storage commissioning
Fuel handling and storage systems — spent fuel pool cooling and cleanup, fuel handling cranes and interlocks, dry cask storage systems — sit at the intersection of mechanical commissioning and criticality safety, where a single missed interlock test is not a punch item but a safety case violation. Deskely holds every crane interlock, pool system and cask loading step in one register, with criticality safety verification built into the gate.
See this scope in detailNuclear balance-of-plant commissioning
Balance-of-plant systems — turbine generator, condensate, feedwater, circulating water, cooling towers — sit outside the nuclear steam supply system but still interface with it directly, and a turbine trip or feedwater transient can challenge the reactor even though the equipment itself is not safety-classified. Deskely holds every balance-of-plant system, interface point and test in one register, keyed to the same discipline used for safety-classified scope but scaled to the correct QA level.
See this scope in detailNuclear instrumentation and control (I&C) upgrade commissioning
Replacing analogue reactor protection and engineered safety features actuation systems with digital platforms is one of the highest-scrutiny modification classes in nuclear commissioning, requiring functional equivalence testing against the original analogue response, cybersecurity qualification and independent verification that common-cause failure has been adequately addressed. Deskely holds the original analogue baseline, the digital platform's qualification record and the site acceptance test in one register, so equivalence is demonstrated with evidence rather than asserted.
See this scope in detailNuclear safety system commissioning and equipment qualification
Engineered safety features — emergency core cooling, containment isolation, emergency diesel generators, safety-related HVAC — depend on equipment qualified to survive the environment it is required to operate in during an accident, and that qualification basis has to be traceable component by component, not inferred by similarity. Deskely holds the qualification basis, the component test record and the safety function verification in one register, so a safety system's commissioning record is defensible against the harshest independent review.
See this scope in detailResearch reactor and fusion facility commissioning
Research reactors, hot cells, irradiation facilities and fusion devices rarely follow a standard commercial reactor's system architecture, but the regulator's expectation for evidence — safety classification, hold points, QA records, radiological controls — does not relax just because the facility is smaller or the design is bespoke. Deskely adapts the same register, ITP and certification model to a facility of any scale, so a university research reactor or a fusion test facility gets the same rigour without importing power-plant-scale overhead it does not need.
